Emergency Backup Freezers
Solar or Battery Powered

What do you do with all the food in your freezer when the power goes out?  Here in Tennessee a couple of days before Christmas several years ago we had an ice storm that took us off the grid for almost six days.  Since it was cold, we moved all the freezer stuff and put it outside in large ice chests.  That was our backup at the time.

Now we have a better plan.

SunDanzer direct current (DC) freezers are specifically designed for high efficiency and low energy consumption to allow refrigeration to operate on the smallest possible energy input from a solar energy system, micro-turbine, wind generator, fuel cell or battery.

Note that you don't have to have a renewable energy source to provide a reliable backup.  A large 12 volt marine battery (or two or three) kept changed by a trickle charger (with charge controller) plugged in to an AC outlet will provide a reliable reserve of power to run a SunDanzer for several days or more depending on the ambient temperature and the amp-hour capacity of the batteries.

SunDanzer also has a 115 VAC power supply option.

The new SunDanzer Model 50L is the smallest and most energy efficient of the SunDanzer models.  See more information about the new SunDanzer Solar Refridgerator Model DCF50L Mini Freezer.

The larger SunDanzer models DCF165 and DCF225 have greater storage capacity but also require more power to keep them running, which means either more battery storage or a shorter time period available for emergency backup.

See the specifications on the DCF165 and DCF225 here.

Your batteries can be charged from your car or truck alternator (not the best idea but better than not having freezer backup) or from a generator, if you have one.  Either way, these highly energy efficient units will use much less power than your conventional household freezer, which will take a load off your generator.

A renewable energy source such as solar panels would be a better alternative for real energy independence.  SunDanzer solar freezers and refrigerators will operate on 75 watts of solar panels in most climates.  The DCF50L will run on less than 45 watts.

SunDanzer features:

  • Top loading chest type design that keeps the cold in the compartment and not running out the bottom freezing your toes

  • Stackable basket design for storage organization

  • Operate on 12 or 24 Volts DC with built in low voltage automatic disconnect for battery protection

  • Use an environmentally friendly refrigerant CFC free R-134a

  • Patented low frost system

  • Rugged scratch resistant galvanized steel exterior

  • Easy to clean aluminum interior with bottom drain hole

  • Lockable lid with interior light

  • Automatic control adjustable thermostat

  • Zero maintenance brushless thermostatically controlled compressor

  • A change in the thermostat installation makes a refrigerator a freezer or vice versa!

  • Super insulated with 4.3 inches (11 centimeters) of polyurethane insulation

  • One year factory warranty

In this age of unpredictable weather events and unpredictable emergency response services, having a backup freezer is a self-reliant sustainable idea.  Keep your food supply safe and secure.  Read more about food security in an emergency here.

A note about freezers versus refrigerators: it typically takes 3 to 4 times as much energy to continuously operate a freezer versus a refrigerator.  Thus, from a total system investment perspective, the best return on investment is to purchase the smallest freezer that will meet your needs.  Situating a solar freezer in a location with the lowest ambient temperature environment also makes a significant difference in the size of the solar system needed for continuous operation, either air conditioned space or in a cellar or basement.
